Chiave per tubi KS Tools 913.1303 22 mm — chiave a testa aperta

ks tools pipe wrench 913.1303 with a 22 mm jaw opening is a Krähenfuss-style (crow's foot) line wrench designed for gripping and turning pipes, fittings and hex fasteners in confined spaces. The compact 22 mm size and the crow's foot profile allow access to recessed nuts and fittings while maintaining firm contact on multiple wrench flats to reduce rounding. The tool is intended for plumbing, maintenance and repair tasks where precise torque transfer and a slim profile are required.

Advantages

The Krähenfuss-style head grips hexagonal fasteners on several flats, improving contact and minimizing slippage compared with open-end wrenches. Its compact form factor and 22 mm opening make it suitable for tight access locations, enabling controlled turning of fittings without needing to remove surrounding components. Robust construction ensures reliable torque transfer, and the design helps protect soft or plated fittings by distributing force over a larger contact area.

Suitable for

• Plumbing work on pipes, couplings and compression fittings in restricted spaces
• Maintenance and repair of machinery where hex fasteners are recessed or hard to reach
• Automotive and HVAC tasks requiring angled or compact access to nuts and fittings

Key specifications

• Jaw opening: 22 mm suitable for 22 mm hex fasteners and fittings
• Style: Krähenfuss (crow's foot) line wrench for improved multi-flat contact
• Application: Designed for pipes, fittings and hex fasteners in confined spaces
• Form factor: Compact profile for restricted access and recessed nuts
• Construction: Sturdy mechanical design for reliable torque transfer

How to use

Select the 22 mm Krähenfuss wrench to match the hex size of the fastener or fitting. Seat the crow's foot firmly onto the hex flats so that the tool makes full contact across multiple sides. Apply steady, controlled torque, maintaining alignment with the fastener to avoid slipping. For confined locations, position the wrench so the handle clearance allows comfortable turning; if necessary, use with an appropriate ratchet or extension compatible with the wrench style. Avoid applying excessive force beyond the intended use to reduce risk of damage to the fastener or tool.

Recommendations

Use the wrench on correctly sized 22 mm hex fittings and avoid striking the tool with a hammer. Inspect the wrench before use for wear or deformation and keep contact surfaces clean to maintain proper grip. For plated or soft fittings, apply torque gradually to reduce the chance of surface damage.
